Subject: [PATCH net-next 4/5] net: ipa: repurpose gsi_irq_ieob_disable()

From: Alex Elder <[email-masked]>
Date: Wed, 20 Jan 2021 16:04:00 -0600

Rename gsi_irq_ieob_disable() to be gsi_irq_ieob_disable_one().

Introduce a new function gsi_irq_ieob_disable() that takes a mask of
events to disable rather than a single event id.  This will be used
in the next patch.

Rename gsi_irq_ieob_enable() to be gsi_irq_ieob_enable_one() to be
consistent.
